Password hashing should be done only with crypt and NEVER with SHA* and MD5 or hash(). The fundamental reason is that crypt is designed to be SLOW which is a VERY good thing for password hashing. It also automatically generate a salt every time which makes pre-computed tables to "decrypt" passwords useless (the generated salt is stored in the returned string for convenience).
